Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

This application note discusses a bidirectional brushed DC motor control employing PIC16F684. It explains how to use Enhanced, Capture, Compare, and PWM (ECCP) on PIC16F684. Low-cost BDC motor control ...

This application note presents Z16FMC microcontroller used to control 3-phase brushless BLDC motors in a sinusoidal PWM modulation mode. It discusses the ways in which to implement sinusoidal PWM ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

Tutorial on ac-motor control based on Clarke and Park transforms. Concepts are presented in stages from top-level through deeper levels of detail. Regardless of their primary field, sooner or later, ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...
